What key combination is used to decrease the size of waveform displays?

The key combination that decreases the size of waveform displays is ALT + CTRL + K. This operation is essential for video editors who need to have precise control over the visual representation of audio in their timeline. Adjusting the size of the waveform can improve workflow by allowing the editor to see more of the timeline at once, helping to distinguish between different audio tracks and edits.

The specific combination of ALT + CTRL + K is designed within Media Composer to facilitate this adjustment efficiently. Familiarity with such shortcuts is crucial for editors in order to streamline their editing processes and maintain a fluid workflow during projects. Understanding the functionality of these shortcuts promotes better organization and management of media elements within the software.
